LDK300/600 Reset Sometimes

[Benjo123]

Hi all
1. In some clients sometimes performs system reset
. Also when I reset the system , the system does not repeat the service immediately, the system performs a self-reset several times.
thanks
Ben

Hi Benjo,

I had a problem similar to this... Check your timeslot allocations.

Also try PGM 450 Flex 8 (System Timer Database Initialization) However make a copy of your system timers at PGM 180; 181 & 182. You will need to reset the system after doing this. - This was my silver bullet to keep the system stable. Things to consider - are you using any bi-directional software on the comms ports? If the problem persists unplug all cords in the comms ports, then see if the system stabilizes. Do you have more than one PRI on a shelf?

To check your timeslot allocations: Use this link...
thread1613-1564087

Or post your SLOT list - like in that thread, then we can guide you.

Also check your grounding of the LG ipLDK300 system. Are all cabinets proper grounded and share a common ground- all of them?We faced similiar issue, where the grounding by mistake had been disconnected, and therefore many strange faults were observed.

And if you use "bi-directional software on the comms ports", then make shure that the connected PC's or servers share the same common ground as the ipLDK-300.
As RS232 /V24 is not a balanced system it is very sensible to noise and vounerable to differencies in grounding, like when your PBX is grounded but the server (PC) is not grounded. This can kick backwards <- to the PBX.
